Comparison of market data providers available as MCP connectors within Claude for Financial Services
The Model Context Protocol (MCP) is an open standard that lets Claude call an external data source live during a conversation. You connect a provider once, and Claude queries it when a question needs it, then folds the result into its answer. Each row below is one such connector. See the ALT/FNDATA connector docs and use-case playbook to get started.
ALT/FNDATA is a secondary-market and private-sale transaction record, USD-normalized with nearest-date FX. The newest one to two quarters undercount while sales are ingested, so read recent trends as provisional. Full coverage and methodology.
